Abstract (en)
[origin: WO2016202574A1] The present invention relates to a method for bonding a polyurethane polymer to a substrate using a multi-layered adhesion approach. Steps of the method include A) selecting a polyurethane polymer to be bonded to the substrate (100); B) depositing an SiO2 layer (200) onto the substrate (100); C) contacting the SiO2 layer (200) with a hydroxysilane compound, thereby forming a first adhesive layer (300) bonded to the SiO2 layer (200); D) contacting the first adhesive layer (300) with a urethane (meth)acrylate compound, thereby forming a second adhesive layer (400) bonded to the first adhesive layer (300); E) contacting the second adhesive layer (400) with a polyurethane (meth)acrylate compound, thereby forming a third adhesive layer (500) bonded to the second adhesive layer (400); F) contacting the third adhesive layer (500) with the polyurethane polymer selected in step A); G) solidifying the polyurethane polymer of step F). The invention further relates to an article obtainable by the method according to the invention, in particular a biomedical implant such as a heart valve stent.
